1. The Way Forward Vancouver, July 22, 2006 Pier Oddone

2. 2 Outline Taking stock The way forward The way forward and Fermilab

3. 3 It has been an extraordinary year… Great progress on the design/cost by GDE Important support in the three regions US: “Raising above the Gathering Storm” President’s Competitiveness Initiative (ACI) EPP2010: “Revealing the Hidden Nature of Space and Time” P5 Initial recommendations Europe: European Strategic Plan Japan: Public Support by Diet Members for hosting ILC in Japan

4. 4 One year anniversary of the GDE Baseline Design: Frascati First roll-up: Vancouver On schedule for RDR! Developing plan for global R&D program

5. 5 “Raising above the gathering storm” National Academy Study: enormous resonance in Washington and elsewhere 900 neighbors showed up for Norm Augustine’s presentation at Fermilab! Key report that led to ACI: doubling of physical sciences budget in 10 years. HEP??

6. 6 EPP2010 Report Extraordinarily supportive of elementary particle physics Extraordinarily supportive of the ILC and of hosting the ILC in the US Broad program with clear recommendations on priorities

7. 7 European Strategic Plan LHC Accelerator R&D: beyond LHC ILC Global Neutrino Program Astrophysics with ApPEC Flavour Physics Nuclear Physics with NuPECC

8. 8 EPP2010 EUROPE LHC ILC Global ILC Hosting Particle Astrophysics Global Neutrino Program Quark Flavour Physics LHC Accelerator R&D ILC Global Neutrino Program Astrophysics Flavour Physics Nuclear Physics

9. 9 P5 Recommendations Highest priorities LHC and ILC Most of the available resources 60% to ILC R&D Maintain breadth of the field with other 40% In FY08 run PEP II and start: Dark Energy Survey (DES) Cold Dark Matter Search Super CDMS-25kg NOvA long base line neutrino program Daya Bay reactor neutrino experiment For the longer term, prepare SNAP and LSST THIS IS A VERY POWERFUL AND EXCITING PROGRAM

10. 10 It will be an extraordinary next year! We will see the conclusion of the RDR It will open a huge range of discussions: Global R&D plan: resources, milestones, schedule of industrial build-up How to carry out the next step: the TDR What is the best industrial model for building the ILC What process for site selection Can we select a site “early” How should the ILC be organized Roles of the existing laboratories in relation to ILC

11. 11 The importance of the RDR Secretary Bodman: How much …….? The RDR is now key element: it determines whether DOE leadership states intent to bid-to-host and makes necessary investment in the R&D.

12. 12 Everyone’s question: where is the line? Most probably there does not exist “a line” EPP2010: assumed a “scale like the LHC” At a fundamental level in the US: do we want to contribute at the forefront of the field ? More importantly: it has to be a credible cost – low elasticity for cost increases (even in the review )

13. 13 The next steps In my opinion, the most critical is to have an integrated international plan to complete the R&D: resources, funding, schedules, milestones Tensions will arise between: regional interests and what we should do together to get there. The latter should have priority – but we should work together to take care of the former as much as possible. The vehicle is the GDE

14. 14 Way Forward: ILC R&D Main Linac Cavity processing technology for a reproducible cavity gradient of 35 MV/m. Fabrication and operation of one ILC rf unit at ILC beam parameters, high gradient, and full pulse repetition rate 10 MW Multi Beam Klystron Low emittance beam transport Large system test Damping Ring (KEK:ATF-I, existing e + e - collider) Understanding of electron cloud Positron Production Beam at IP (KEK:ATF-II)

15. 15 The next steps We need to increase understanding across the regions: very different pressures; different times at which resources are “freed up”. An aggressive posture to host the ILC in any region (like EPP2010) is good. Three is best! Working in other aspects of elementary particle physics globally will be critical. All regions should stay strong.

16. 16 The next steps Ultimately the physics reach will carry the day: need to continue efforts to develop and present the case broadly to many parties

17. 17 Meanwhile at Fermilab……. Very strong shift of available resources last year to ILC. But we still have to run the Tevatron (9 accelerators!) Roughly $25M investment in people, infrastructure and R&D this fiscal year. We are creating several mechanisms to increase physicists involvement in broad collaborative efforts with the community.

18. 18 Cavity R&D To speed progress on the ILC cavities gradient goal with the GDE have taken an approach that Maximizes the utilization of existing U.S. SRF infrastructure Develops Fermilab expertise and infrastructure in parallel AES ACCEL 60 Cavities (by FY07)

19. 19 Main ILC R&D activities Main Linac activities: Accelerator physics design in support of the RDR Demonstrate feasibility of all Main Linac technical components Engineering design of ML technical systems Estimates of the ML cost & methods for cost reduction U.S. Industrialization of high volume ML components Civil and Site Development activities: Civil engineering of machine enclosures Study U.S. sites on or near the Fermilab site Estimate costs for conventional facilities In FY07 we hope to begin a site specific ILC study

20. 20 All done in broad collaborations Electron Source: BNL, NIU Damping Ring Design: Accelerator Physics: ANL,LBNL Development of fast kicker: UIUC & Cornell ATF-II technical & collab board, Beam inst tests: KEK SCRF materials R&D: UW,NW, MSU, Cornell, DESY, KEK, NHMFL, etc

23. 23 Civil and Site Development Goal: Determine the best possible site for an ILC in Illinois With the GDE we are developing the ILC Civil Design Tunnel Design (diameter, # shafts, laser-straight vs curved) Site specific machine and Civil design will start in FY07 Geological, environmental, community impact studies not to scale ~30 km x2 R = 955m E = 5 GeV ML ~10km (G = 31.5MV/m)  3.2 m  5.5 m  4.5 m not to scale RDR FNAL site f Fermilab

24. 24 ILC Task Force Commissioned two month ago: Fermilab’s High Energy Physicists involvement Collaboration with other labs and universities The entire task force has been meeting ~weekly Review world-wide ILC R&D efforts Accelerator - Bob Kephart Beam instrumentation - Marc Ross Detector - Jim Brau Review Fermilab ILC R&D efforts

25. 25 ILC-HEP Task Force Issues raised concerning university groups Funding Slow How to increase/redirect base program funds to ILC? Attracting graduate students and postdocs to ILC projects Hardware (ILC R&D) + Data Analysis (e.g. CDF or DØ) Forming working groups: Accelerator technologies and simulation Beam Instrumentation and machine interface Detector R&D, physics and simulation Test Beam Facilities

26. 26 Fermilab Group: Building the Momentum Have created common interest internal group on ILC Seminar / lecture series Joe Lykken and Bob Tschirhart to lead this effort Possible topics are ILC Physics First years’ LHC physics for the ILC Polarization Accumulating e + e - knowledge at Fermilab Heavy flavor tagging issues Jet energy resolution issues Weekly (Wednesday) lunch exchange ideas, problems/solutions, and build a team sprit Complements the task force

27. 27 International Fellowships at Fermilab Improve connections to scientists and institutions world- wide. Bring ~6 students, postdocs, and scientists from foreign institutions to work at Fermilab for up to 3 years. URL: http://www.fnal.gov/pub/forphysicists/fellowships/international/ http://www.fnal.gov/pub/forphysicists/fellowships/international/ In the initial years, the program has two main objectives. Maximize results pouring out of the Tevatron experiments Help Fermilab and the community further engage in ILC efforts
